Abstract
When producing duplex copies from simplex original documents, the documents can be fed from the final page, but the copying method must be varied between the odd-number documents and even-number documents. Accordingly, the number of documents is counted while copying every other document from the final page, and the copying method is changed between the odd-number documents and even-number documents. Therefore, it is not necessary to count the number of documents before starting copying, and the time and labor required for producing duplex copies may be saved. Moreover, the copying apparatus can maintain the face-back relation during conveying and can invert the face-back relation during conveying the originals from storage into the exposure region, and also comprises the same two types of conveyors as the conveyors for the originals which two types convey from the exposure region to storage. Therefore, by using these four conveyors depending on the copying method and the document stacking state in storage, the original conveying time may be shortened, so that the time and labor required for producing duplex copies may be saved.
